5 Claims. 7 (01.108-26) This invention relates to flashings for roofing,or the like, and is more particularly related to the flashing of brickor other masonic walls.

In the connecting of angular walls to form a Waterproof connection, asfor example in the connecting of roofing with a fire wall, deck wall,

wall parapet or the like flashing and counterfla'shing have heretoforebeen utilized. The particular problem presented, however, has been to soconnect such a wall with a roofing material as to enable the formationof a waterproof connection in an inexpensive manner, using a minimum oflabor, to provide a neat appearing connection which is readilydetachable to permit inspection h provide a means of forming awaterproof connection between a roofing or wall material and a masonicwall, which will be of permanent char- 'acter, easily applied, orremoved as desired or required.

Another object of this invention is to provide a means of forming awaterproof connection between a masonic wall anda roofing or like wall,floor or roof material which includes a flashing adapted to be embeddedwithin and secured to the masonic structure, a counterflashing adaptedto overli the said wall material, and an interlocking means forreleasably connecting the flashing and the counterflashing, and whereina waterproof or resisting connection is formed between the flashing andcounterflashing.

Other objects and advantages of my invention it is believed will beapparent from the following detailed description of a preferredembodiment thereof as illustrated in the accompanying drawing, whereinfor convenience I have illustrated my invention as in use in flashing abrick fire wall to a composition sheet roofing. It will be apparent tothose skilled in the art that this illustration is only one adaptationof my invention given for the purpose of description, explanation of itsprinciples and mode of operation.

In the drawing:

Fig. 1 is a perspective view of a roof or deck and fire wallillustrating the flashing as embodying my invention as adapted thereto.

Fig. 2 is a fragmental transverse perspective section thereof duringlaying of the brick or other masonic block or stone.

Fig. 3 is a detached fragmental perspective sectional view of theflashing and counterflashing of my invention.

'2 formed of suitable concrete.

Fig. 4 is a detached perspective view of the flashing tie plate of myinvention.

Fig. 5 is a detached perspective view of the locking band embodied in myinvention illustrating in dotted lines the band as bent to lockingposition.

Fig 6 is a fragmental sectional perspective view of a modified form offlashing, counterflashing and releasable locking means embodying myinvention.

Fig. 7 is a detached fragmental perspective view of the counterflashingand attached locking band of my invention as illustrated in Fig. 6.

The preferred embodiment of my present invention is particularly adaptedfor use in connection with brick, stone, or other masonic walls whereinthe wall structure is constructed of superimposed bricks or the likeconnected together through the medium of suitable mortar, cement, or thelike.

In this modification of my invention the deck or fire wall I isillustrated asofvsuch masonic structure connected at the edge of aroofor deck Roofing material 3. which may be any suitable material which iscommonly referred to as roofing paper, composition or metal, is laidupon the surface of the roof 2 so that its edge portions 4 extend up theinner surface of the wall 1. The flashing. embodying my inventionincludes flashing members 5 which are laid in the masonic. wall I duringits construction between the bricks or othermembers forming the wall.Thus the flashing members 5 are positioned as indicated in Figure 2 andare secured in position through the medium of their horizontal flanges lwhich terminate in the hook flange 8. The vertically extending skirt 9of the flashing 5 terminates at its lower end in an outwardly divergingsecuring flange l0 having locking means receiving recesses IL. Theflashing 5 is held in position by means of tie straps l2 which are soformed as to include a locking detent l3 into which the hook flange 8fits and at its opposed ends with downwardly extending holding flangesI4 and I5 which are spaced apart a distance corresponding with the widthof bricks 6 or other masonic element used in the formation of the wallI.

The members [2 are formed of a bendable material such as galvanizedplate so that they may be bent to conform with the dimensions of thesaid masonic members, particularly at their rear flanges l5. After theflashing 5 is thus secured in position, the mortar, cement or othermaterial is spread over the members 12 and. the horizontal flanges 1 andthe next layer of bricks or the like added until the wall is completed.Thus the flashing 5 is embedded within the cementitious material used toform the masonic Wall I. The counterflashing It in this modification ofmy invention may consist merely of a strip of galvanized sheet metal ofsuch width as to extend under the skirt 9 and over the upturned edge 4of the roofing material 3. When thus positioned, the counterflashing I6is secured in position through the use of locking strips H which arepreferably formed at their lower end to provide hook sections I8 whichare adapted to book under the edge of the counterflashing IS. The upperlocking ends of the strip 11 are then extended through the recesses IIand bent over as indicated at I9 to lock the counterflashing IS inposition. During this locking, a definite tension is imposed upon thelocking strips [1 as they are bent over the angular flange I so that theyielding of this angulated flange provides a resilient holding inposition of the counterflashing [6 whereby the upper edge 4 of theroofing material 3 is clamped against the inner surface of the wall I.

In case repair or re-roofing or inspection of the roofing is required atany time, this may easily be accomplished by merely removing the lockingstrip l1 and the counterflashing [6, thereby enabling easy access to theupper edge of the roofing material 4. Obviously the flashing may beagain completed after inspection without the necessity of providing newor additional counterflashings or securing means.

In the modified form of my invention as illustrated in Figures 6 and 7,similar parts have been indicated with similar numerals with theaddition of an exponent a thereto.

In this modification of my invention, all parts are similar to thoseheretofore described with the exception of the locking strips I! whichare here illustrated as being secured through the use of suitablesecuring elements such as riveting or welding the same to the face ofthe counterflashing I6 as indicated at 20 In this modification of myinvention the locking strips I! are'slightly bent outward so that theymay be easily inserted through the locking recesses Il of the flashingto be bent over as indicated at H in the same manner as described inconnection with the first modification of my invention.

In order to prevent undue rubbing and wear of the upwardly extendingportion 4 of the roof 3, I prefer to bend the material forming thecounterflashing l6 and I6 upon itself as indicated at 2| and 2|respectively.

Having fully described my invention, it is to be understood that I donot wish to be limited to the details herein set forth, but my inventionis of the full scope of the appended claims.
